Lama Patent No. 86,161, dated January 26,1869.

IMPROVED CAR-COUPLING.

To all whom it may concern Be it known that we, OYZ. HURD and J OHN W. Annnvenn, of Mount Pulaski, in the county of Logan, and State-of Illinois, have invented a new and useful Improved Oar-Ooupling, of which the following is a full, clear, and exact description, reference being had to the annexed drawing, making a part of this specification, in which- "Figure 1 represents a perspective view of ourinvention.

- Figure 2 represents a longitudinal sectional elevation of same.

Similar letters indicate like parts.v n

The object we wish tov obtain is to be able to couple cars without the necessity of any one going between them for the purpose, and also to uncouple them with ease.

The draw-head A, figs. 1, 2, is cast with an opening, B, in one end, extending only about half its length, End the four sides of its mouth bevelled, as seen in 1. To the roof of the mouth is pivoted a plate, 0, nearly as wide as the opening, but short enough to leave a considerable space between its lower edge and the bottom of the mouth.

To one end of the pivot on which 0 swings is attached an arm, a, which, by means of the link b, is'

connected with the arinc of the shaftd, which, having its bearings in F, is, at its other end, connected with a crank, g, having'fat its extremity, the coupling-pin p, figsfi l, 2, which passes through the draw-head, as seen in 2 T? g is attached a cord, 0 or a rod may be used, if preferred. V

The connecting-link H is made with two shoulders on either end, a n n" n and a only being shown in fig. 1, and a in fig. 2. v

The space between the edge of the plate 0 andv the:

bottom of the mouthof the draw-head is suficient to allow the passage of the head, n, of the link till it reaches the shoulders, but these, striking against the plate, force it back, and, by the connections of the plate with the coupling-pin, raise the same till the link has passed beyond it, when, on account of the ch'amfering of the shoulders, the pressure against the plate is removed, and the same swings back to its for mer-place, and the pin drops, and completes thecouplin y reason of the bevelling of themout-h of the drawhead, it is evident that the link has sufiicient play while in use, and, when in the act of coupling, can approach at an angle, even.

The back of the mouth of the draw-head is made small enough to prevent the link from playing too much either-way, and thus prevent the coupling.

To uncouple, it is only necessary to pull the cord 0,'

which may be carried to the top of the car, or to any other point desired.

To prevent the arm a from rising too far, a stud, s, is arranged as shown.

life do not, of course, claim to be the inventors of automatic car-couplings, nor any originality in the use of a pin and link to connect cars, since there are many kinds of the former, and the use of the latter is common; but i \Vhat we do claim as our invention, and desire to secure by Letters Patent, is-

The draw-head A, plate 0, and arm g, with their connections, pin p, and link H, all arranged, constructed, and operated, in relation to each other, substantially as and for the purposes shown and specified.
